I just saw T mobile tourist plan. 3 weeks @ 30$. https://prepaid-phones.t-mobile.com/prepaid-international-tourist-plan<p>Are there any other options?
Cricket is quite cheap too. <a href="https://www.cricketwireless.com/" rel="nofollow">https://www.cricketwireless.com/</a>
The price should be comparable to T-mobile, but they run on top of a different network (AT&T). Not sure which one is better though.
My Thai phone service has a deal for price capped all-you-can-eat mobile data roaming, so I used that (and had several colleagues use it as a hot spot).
